Unit thickness sensitivity kernels of the modeled M₂ OTL displacements. The modeled M₂ OTL displacements are predicted at 24.5°N on Taiwan Island to + 10% linear perturbations of the density (left), bulk modulus (middle), and shear modulus (right) in the upper crust (black), middle crust (green), lower crust (blue), LID (magenta), LVZ (red), and region above the transition zone (yellow) of TW1. The depths of the perturbed layers: the upper crust (0–13.88 km depth), middle crust (13.88–24.52 km depth), lower crust (24.52–32.15 km depth), LID (32.15–80 km depth), LVZ (80–220 km depth), and region above the transition zone (220–400 km depth)
